unable to create new project or new folder

I cannot create new projects or folders either on Windows 10 nor on the MindJet website. I have a Mindjet Connect Free folder/project(??? it has a cloud icon, but not sure how that matters???) that shows up in the Projects or Folders view, depending on what I'm using. In neither case are the New Folder or New Projects buttons available. (They're there, but muted out.)
I'd really love to start organizing my projects. Please help!
Much appreciated,
John
